I am a Ph.D. student in the group of Prof. Barak Kol. We are currently working on scattering amplitudes. Recently we have discovered the connection between tree-level color structures in pure Yang-Mills and the cyclic Lie Operad.
I am also an artist. My paintings have been showcased in several exhibitions in Israel and on July 2013 some of my paintings were displayed in an international exhibition at the Museum of History of Minsk in Minsk, Belarus. I also play the piano and participate in concerts. My paintings can be seen in our family's gallery website www.shirgallery.com.
